GEORGE E. RICHARDSON, or c oLEBRooK, NEW HAMrsHIRn FLUSH vALvn Application led August 3, 1922.' Serial No. 579,514.

To all 'whom z't may concern.'

Be it known that I, GEORGE E. RICHARDSON, county of Coos, and State of' New Hampshire, a citizen of the. United States, have invented certain new and useful Improvements in Valves, of which the following is a specifisis cation, reference being had to the accompanying drawings, forming a part thereof.

My invention relates to lus valves for tanks such as are used for water closets and' has forl its object to provide a flush valve of this type which will be inexpensive in construction, eectivev in operation not liable to et out of order and in which the valve an valve seat may be' readily gotten at-to permit of `repair or renewal of worn or defective parts and will permit the use of a spherical valve. l

With the above indicated objects and other objects hereinafter explained in view my invention consists in the construction and combination of elements hereinafter described and claimed.'-

Referring to the drawings:

Figure .1 is' a side view, partly broken away showing a complete 'liush valve embodying my invention.

Figure 2 isa central sectional view of the valve seat and f 4 Figure 3 is a top plan view of the cage for the ball servingas the valve.

In the drawings 1 indicates a hollow base plate from which outlet pipe 2 leads downward and overflow pipe 3 leads upward both outlet pipe and overflow pipe communicating with the interior of the base .plateso that water passing down the `overflow pipe will iiow through the base lateinto the upper` end of the outlet pipe. In the upper plate of the base plate 1, directly above and-in line lto with the outlet pipe is a circular opening. 4 having in its wall a groove 5 to receive a packing ring or gasket 6 of rubber or like material,'preferably in the form of a solid ring as shown, which forms a seat for a. ball 7 of considerably larger diameter than the diameter of the opening 4 so that when in position the centre of the ball :will be a considerable 'distance abovev the base plate.. A

Surrounding the opening 4 and resting on the upper surface of the base rplate is a ring 8 carrying the lower ends of U-shaped strips 9 and 10 extending'upward and arranged to cross at their upper ends of the -Us so as to Flush Y simple and A normally rests on ring 8 about the form a cage in which the ball 7 is free to rise and fall within the limit of the height of these U shaped strips. This ring 8 is so secured on thebase plate as to be readily detached to permit the ball 7 to be removed or replaced, the means for this purpose shown comprising keyhole slots 11, 12, and 13.formed in the ring, the enlarged portions of these slots being adapted to fit over the heads of headed pins 14, 15, and 16 carriedI by the base plate and the narrow portions of the slots being of less width than the diameters of the heads so that when the ringis placed in pins and is then rotated the narrower por'- tions of the slots will fit about the pins beneath their heads and the ring will thus be held from removal. To prevent the ring from being accidentally rotated so as to free it from engagement with the pins, a latch 17 is pivoted on the ring sov that it may be turned into position to engage one of the pins.

tween the overflow vpipe 3 and the openin 4 is arranged a lug 18 in which is pivot/ed a lever 19 the free end of which extends toward the openin 4 and carries atits end a ring 20 of a diameter. somewhat greater than the diameter of than the diameter of the ball. This ring yopenin 4 within the lower ends of the U shaped strips 9 and 10. On the upper side of the lever 19 is a lug 21 in which is pivoted the lower end of an operatingl rod 22 by which the lever :may be operated to lift the ring 20. The ball v7 may be hollow rubber ball as is usual in iiush valves but is preferably Va hollow glass ball.- It should be of such specific 'gravityfthat when the tank (not shown) in which the iush valve is placed is full and the ballv is lifted from its seat, it will fioat upward within the limit permitted by the cage formed by the U shaped strips nearly all of it has run out of the tank the ball will fall to its seat and, 'as the tank refills, will be held to its seat by the ressure of the water until forcibly lifted om its seat bythe lifting of the ring 30.

Havin thus described my invention, what I claim is In a Iflush valve, a base plate having an outlet therein, a recess extending about the outlet, a tubular washer arranged within position with the enlarged,i

the opening 4 but less 9 and 10, and when the watei or said recess and forming a seat for `a, valve,

l e spherical valve of a diameter greater than the diameter of said valve seat and adapted to rest' upon said tubular Washer, aflever 'pivoted to the upper side ont the bese plate and provided on its free end with a, ring extending above the valve seat but below the horizontal plane of the centerof the spherimeans for limiting the upward movement K of the spherical `valve when displaeed from '1,5

its seatgeomprisino' a, ring provided with keyhole Aslots and avin U shaped strips secured thereto; the base p ate being provided With headed pins adapted to enter the enlarged portionsof the keyhole slots, and a 20 locking` means attached to the `ring comprising a'pivoted member-provided with a. recess adapted to encircle said headed vpin against disengagement.

In testimony whereof signtaure.2
